Byte[] -> String: use system.convert.tobase64string

Convert.ToBase64String(byte[] data)

String -> Byte[]: use system.convert.frombase64string

Convert.FromBase64String(string data)

Let's keep this as simple as possible.

let i = 1
console.log('A', i)    // 1
console.log('B', ++i)  // 2
console.log('C', i++)  // 2
console.log('D', i)    // 3

A) Prints the value of i. B) First i is incremented then the console.log is run with i as it's new value. C) Console.log is run with i at its current value, then i will get incemented. D) Prints the value of i.

In short if you use the pre-shorthand i.e(++i) i will get updated before the line is executed. If you use the post-shorthand i.e(i++) the current line will run as if i had not been updated yet then i gets increased so ther next time your interpreter comes accross i it will have been increrased.

Sample usage while creating a table:

[ColumnName]     BIT   NULL   DEFAULT 0

Hi I add key and value to each object

let persons = [_x000D_
  {_x000D_
    name : "John Doe Sr",_x000D_
    age: 30_x000D_
  },{_x000D_
    name: "John Doe Jr",_x000D_
    age : 5_x000D_
  }_x000D_
]_x000D_
_x000D_
function addKeyValue(obj, key, data){_x000D_
  obj[key] = data;_x000D_
}_x000D_
 _x000D_
_x000D_
let newinfo = persons.map(function(person) {_x000D_
  return addKeyValue(person, 'newKey', 'newValue');_x000D_
});_x000D_
_x000D_
console.log(persons);

SQL Server 2012 and Later

Just use Try_Convert instead:

TRY_CONVERT takes the value passed to it and tries to convert it to the specified data_type. If the cast succeeds, TRY_CONVERT returns the value as the specified data_type; if an error occurs, null is returned. However if you request a conversion that is explicitly not permitted, then TRY_CONVERT fails with an error.

Read more about Try_Convert.

SQL Server 2008 and Earlier

The traditional way of handling this is by guarding every expression with a case statement so that no matter when it is evaluated, it will not create an error, even if it logically seems that the CASE statement should not be needed. Something like this:

SELECT
   Account_Code =
      Convert(
         bigint, -- only gives up to 18 digits, so use decimal(20, 0) if you must
         CASE
         WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
         ELSE X.Account_Code
         END
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      CASE
      WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
      ELSE X.Account_Code
      END
   ) BETWEEN 503100 AND 503205

However, I like using strategies such as this with SQL Server 2005 and up:

SELECT
   Account_Code = Convert(bigint, X.Account_Code),
   A.Descr
FROM
   dbo.Account A
   OUTER APPLY (
      SELECT A.Account_Code WHERE A.Account_Code NOT LIKE '%[^0-9]%'
   ) X
WHERE
   Convert(bigint, X.Account_Code) BETWEEN 503100 AND 503205

What this does is strategically switch the Account_Code values to NULL inside of the X table when they are not numeric. I initially used CROSS APPLY but as Mikael Eriksson so aptly pointed out, this resulted in the same error because the query parser ran into the exact same problem of optimizing away my attempt to force the expression order (predicate pushdown defeated it). By switching to OUTER APPLY it changed the actual meaning of the operation so that X.Account_Code could contain NULL values within the outer query, thus requiring proper evaluation order.

You may be interested to read Erland Sommarskog's Microsoft Connect request about this evaluation order issue. He in fact calls it a bug.

There are additional issues here but I can't address them now.

P.S. I had a brainstorm today. An alternate to the "traditional way" that I suggested is a SELECT expression with an outer reference, which also works in SQL Server 2000. (I've noticed that since learning CROSS/OUTER APPLY I've improved my query capability with older SQL Server versions, too--as I am getting more versatile with the "outer reference" capabilities of SELECT, ON, and WHERE clauses!)

SELECT
   Account_Code =
      Convert(
         bigint,
         (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
   ) BETWEEN 503100 AND 503205

It's a lot shorter than the CASE statement.

You can execute a subshell and redirect all output while still putting the process in the background:

( ./script.sh blah > ~/log/blah.log 2>&1 ) &
echo $! > ~/pids/blah.pid

If you put this on onDestroy or onStop method. I think that when the activity has been created again the MessageReciver wasn't being created.

@Override 
public void onDestroy (){
    super.onDestroy();
LocalBroadcastManager.getInstance(context).unregisterReceiver(mMessageReceiver);

}

If you want only letters - so from a to z, lower case or upper case, excluding everything else (numbers, blank spaces, symbols), you can modify your function like this:

function validate() {
    if (document.myForm.name.value == "") {
        alert("Enter a name");
        document.myForm.name.focus();
        return false;
    }
    if (!/^[a-zA-Z]*$/g.test(document.myForm.name.value)) {
        alert("Invalid characters");
        document.myForm.name.focus();
        return false;
    }
}

To get the index values as a list/list of tuples for Index/MultiIndex do:

df.index.values.tolist()  # an ndarray method, you probably shouldn't depend on this

or

list(df.index.values)  # this will always work in pandas

It is working you have to check attr after assigning value

LiveDemo

$('#amount').attr( 'datamin','1000');

alert($('#amount').attr( 'datamin'));?

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

Among other things, it can be used for security. If you have a "customer" table, you might want to give all of your sales people access to the name, address, zipcode, etc. fields, but not credit_card_number. You can create a view that only includes the columns they need access to and then grant them access on the view.

I had much better luck testing locally using 127.0.0.1 as the domain. I'm not sure why, but I had mixed results with localhost and .localhost, etc.

I use GUIDs as random keys for database type operations.

The hexadecimal form, with the dashes and extra characters seem unnecessarily long to me. But I also like that strings representing hexadecimal numbers are very safe in that they do not contain characters that can cause problems in some situations such as '+','=', etc..

Instead of hexadecimal, I use a url-safe base64 string. The following does not conform to any UUID/GUID spec though (other than having the required amount of randomness).

import base64
import uuid

# get a UUID - URL safe, Base64
def get_a_uuid():
    r_uuid = base64.urlsafe_b64encode(uuid.uuid4().bytes)
    return r_uuid.replace('=', '')

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

Check out the FIND() function in Excel.

Syntax:

FIND( substring, string, [start_position])

Returns #VALUE! if it doesn't find the substring.

Try doing this :

awk '{print substr($0, 1, length($0)-1)}' file.txt

This is more generic than just removing the final comma but any last character

If you'd want to only remove the last comma with awk :

awk '{gsub(/,$/,""); print}' file.txt

You need allow ip based access for tomcat in server.xml, by default its disabled. Open server.xml search for "

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           URIEncoding="UTF-8"
           redirectPort="8443" />

Here add a new attribute useIPVHosts="true" so it looks like this,

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           URIEncoding="UTF-8"
           redirectPort="8443"
           useIPVHosts="true" />

Now restart tomcat, it should work

This should work as well

text = 'the car? was big and* red!'

newtext = re.sub( '[^a-z0-9]', ' ', text)

print(newtext)

the car was big and red

index.html

<!DOCTYPE html>
<html>
   <body>
       <form action="submit.php" method="POST">
         First name: <input type="text" name="firstname" /><br /><br />
         Last name: <input type="text" name="lastname" /><br />
         <input type="submit" value="Submit" />
      </form> 
   </body>
</html>

After that one more file which page you want to display after pressing the submit button

submit.php

<html>
  <body>

    Your First Name is -  <?php echo $_POST["firstname"]; ?><br>
    Your Last Name is -   <?php echo $_POST["lastname"]; ?>

  </body>
</html>

At least on text inputs, it appears that onChange is listening for input events:

var event = new Event('input', { bubbles: true });
element.dispatchEvent(event);

With ASP.NET, you need to consider the reference point for a "relative URL" - is it relative to the page request, a user control, or if it is "relative" simply by virtue of using "~/"?

The Uri class contains a simple way to convert a relative URL to an absolute URL (given an absolute URL as the reference point for the relative URL):

var uri = new Uri(absoluteUrl, relativeUrl);

If relativeUrl is in fact an abolute URL, then the absoluteUrl is ignored.

The only question then remains what the reference point is, and whether "~/" URLs are allowed (the Uri constructor does not translate these).

japf has answer it correctly. Just in case if you are looking at multi-line actions, you can write as below.

Application.Current.Dispatcher.BeginInvoke(
  DispatcherPriority.Background,
  new Action(() => { 
    this.progressBar.Value = 50;
  }));

Information for other users who want to know about performance:

If your code NEED to be written for high performance, you can first check if the invoke is required by using CheckAccess flag.

if(Application.Current.Dispatcher.CheckAccess())
{
    this.progressBar.Value = 50;
}
else
{
    Application.Current.Dispatcher.BeginInvoke(
      DispatcherPriority.Background,
      new Action(() => { 
        this.progressBar.Value = 50;
      }));
}

Note that method CheckAccess() is hidden from Visual Studio 2015 so just write it without expecting intellisense to show it up. Note that CheckAccess has overhead on performance (overhead in few nanoseconds). It's only better when you want to save that microsecond required to perform the 'invoke' at any cost. Also, there is always option to create two methods (on with invoke, and other without) when calling method is sure if it's in UI Thread or not. It's only rarest of rare case when you should be looking at this aspect of dispatcher.

I use the following format and works well.

robocopy \\SourceServer\Path \\TargetServer\Path filename.txt

to copy everything you can replace filename.txt with *.* and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html

You can also add new json objects into your json, using the extend function,

var newJson = $.extend({}, {my:"json"}, {other:"json"});
// result -> {my: "json", other: "json"}

A very good option for the extend function is the recursive merge. Just add the true value as the first parameter (read the documentation for more options). Example,

var newJson = $.extend(true, {}, {
    my:"json",
    nestedJson: {a1:1, a2:2}
}, {
    other:"json",
    nestedJson: {b1:1, b2:2}
});
// result -> {my: "json", other: "json", nestedJson: {a1:1, a2:2, b1:1, b2:2}}

decimal.js, big.js or bignumber.js can be used to avoid floating-point manipulation problems in Javascript:

0.1 * 0.2                                // 0.020000000000000004
x = new Decimal(0.1)
y = x.times(0.2)                          // '0.2'
x.times(0.2).equals(0.2)                  // true

big.js: minimalist; easy-to-use; precision specified in decimal places; precision applied to division only.

bignumber.js: bases 2-64; configuration options; NaN; Infinity; precision specified in decimal places; precision applied to division only; base prefixes.

decimal.js: bases 2-64; configuration options; NaN; Infinity; non-integer powers, exp, ln, log; precision specified in significant digits; precision always applied; random numbers.

The size of arrays in Java cannot be changed. So, technically you cannot remove any elements from the array.

One way to simulate removing an element from the array is to create a new, smaller array, and then copy all of the elements from the original array into the new, smaller array.

String[] yourArray = Arrays.copyOfRange(oldArr, 1, oldArr.length);

However, I would not suggest the above method. You should really be using a List<String>. Lists allow you to add and remove items from any index. That would look similar to the following:

List<String> list = new ArrayList<String>(); // or LinkedList<String>();
list.add("Stuff");
// add lots of stuff
list.remove(0); // removes the first item

First of all, my response to the question you've originally asked

Q: How do I discover if a variable is defined at a point in my code?

A: Read up in the source file until you see a line where that variable is defined.

But further, you've given a code example that there are various permutations of that are quite pythonic. You're after a way to scan a sequence for elements that match a condition, so here are some solutions:

def findFirstMatch(sequence):
    for value in sequence:
        if matchCondition(value):
            return value

    raise LookupError("Could not find match in sequence")

Clearly in this example you could replace the raise with a return None depending on what you wanted to achieve.

If you wanted everything that matched the condition you could do this:

def findAllMatches(sequence):
    matches = []
    for value in sequence:
        if matchCondition(value):
            matches.append(value)

    return matches

There is another way of doing this with yield that I won't bother showing you, because it's quite complicated in the way that it works.

Further, there is a one line way of achieving this:

all_matches = [value for value in sequence if matchCondition(value)]

Another thing you can do is just drag a folder from your computer into the GitHub repository page. This folder does have to have at least 1 item in it, though.

ViewBag and ViewData are two means which are used to pass information from controller to view in ASP.Net MVC. The goal of using both mechanism is to provide the communicaton between controller and View. Both have short life that is the value of both becomes null once the redirection has occured ie, once the page has redirected from the source page (where we set the value of ViewBag or ViewData) to the target page , both ViewBag as well as ViewData becomes null.

Despite having these similarities both (ViewBag and ViewData) are two different things if we talk about the implementation of both. The differences are as follows :

1.) If we analyse both implementation wise then we will find that ViewData is a dictionary data structure - Dictionary of Objects derived from ViewDataDictionary and accessible using strings as Keys to these values while ViewBag makes use of the dynamic features introduced in C#4.0 and is a dynamic property.

2.) While accessing the values form ViewData , we need to typecast the values (datatypes) as they are stored as Objects in the ViewData dictionary but there is no such need if we are accessing th value in case of ViewBag.

3.) In ViewBag we can set the value like this :

      ViewBag.Name = "Value"; 

and can access as follows:

          @ViewBag.Name

While in case of ViewData the values can be set and accessed as follows: Setting ViewData as follows :

ViewData["Name"] = "Value";

and accessing value like this

 @ViewData["Name"]

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):

select myintfield + 0.0 as myfloatfield from mytable

While @Heximal's answer works, I don't personally recommend it.

This is because it uses implicit casting. Although you didn't type CAST, either the SUM() or the 0.0 need to be cast to be the same data-types, before the + can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +. But SUM(aFloatField) + 0 does not yield an INT, because the 0 is being implicitly cast to a FLOAT.

I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.

If you want to be explicit, I would use the following.

CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT  requires 8.0

You can try the following to see what happens...

CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))

You should be able to use OrderBy in LINQ...

var sortedItems = myList.OrderBy(s => s);

For Spooling in Oracle SQL Developer, here is the solution.

set heading on

set linesize 1500

set colsep '|'

set numformat 99999999999999999999

set pagesize 25000

spool E:\abc.txt

@E:\abc.sql;

spool off

The hint is :

1. when we spool from sql plus , then the whole query is required.

2. when we spool from Oracle Sql Developer , then the reference path of the query required as given in the specified example.

SQL 2003 standard defines the format as follows:

<unquoted timestamp string> ::= <unquoted date string> <space> <unquoted time string>
<date value> ::= <years value> <minus sign> <months value> <minus sign> <days value>
<time value> ::= <hours value> <colon> <minutes value> <colon> <seconds value>

There are some definitions in between that just link back to these, but in short YYYY-MM-DD HH:MM:SS with optional .mmm milliseconds is required to work on all SQL databases.

The best way for DateTime is use a Trigger:

/************ ROLE ************/
drop table if exists `role`;
create table `role` (
    `id_role` bigint(20) unsigned not null auto_increment,
    `date_created` datetime,
    `date_deleted` datetime,
    `name` varchar(35) not null,
    `description` text,
    primary key (`id_role`)
) comment='';

drop trigger if exists `role_date_created`;
create trigger `role_date_created` before insert
    on `role`
    for each row 
    set new.`date_created` = now();

Using a button tag instead of the input, resetting it and put a span inside, you'll then just have to style both the link and the span in the same way. It involve extra markup, but it worked for me.

the markup:

<button type="submit">
    <span>submit</span>
</button>
<a>cancel</a>

the css:

button[type="submit"] {
    display: inline;
    border: none;
    padding: 0;
    background: none;
}

Found the easiest way, python to the rescue :D

colorsys.hls_to_rgb(h, l, s)

Convert the color from HLS coordinates to RGB coordinates.

Also:

func getTime() -> (hour: Int, minute: Int,second: Int) {
    let hour = 1
    let minute = 2
    let second = 3
    return ( hour, minute, second)
}

Then it's invoked as:

let time = getTime()
print("hour: \(time.hour), minute: \(time.minute), second: \(time.second)")

This is the standard way how to use it in the book The Swift Programming Language written by Apple.

or just like:

let time = getTime()
print("hour: \(time.0), minute: \(time.1), second: \(time.2)")

it's the same but less clearly.

You should use window.history and return a false so that the href is not navigated by the browser ( the default behavior ).

<a href="www.mypage.com" onclick="window.history.go(-1); return false;"> Link </a>

You want something like:

<appSettings>
  <add key="developmentModeUserId" xdt:Transform="Remove" xdt:Locator="Match(key)"/>
  <add key="developmentMode" value="false" xdt:Transform="SetAttributes"
          xdt:Locator="Match(key)"/>
</appSettings>

You can use this function to get proper client IP:

public function getClientIP(){       
     if (array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER)){
            return  $_SERVER["HTTP_X_FORWARDED_FOR"];  
     }else if (array_key_exists('REMOTE_ADDR', $_SERVER)) { 
            return $_SERVER["REMOTE_ADDR"]; 
     }else if (array_key_exists('HTTP_CLIENT_IP', $_SERVER)) {
            return $_SERVER["HTTP_CLIENT_IP"]; 
     } 

     return '';
}

Take a look at Simple JavaScript Inheritance and Inheritance Patterns in JavaScript.

The simplest method is probably functional inheritance but there are pros and cons.

Is there a command that does?

If you have tried everything regarding this issue to no avail, you'll end up where I did. It turns out, Amazon's existing CORS setup directions work just fine... just make sure you remember to redeploy! The CORS editing wizard, even with all its nice little green checkmarks, does not make live updates to your API. Perhaps obvious, but it stumped me for half a day.

The simplest way to log to file and to stderr:

import logging

logging.basicConfig(filename="logfile.txt")
stderrLogger=logging.StreamHandler()
stderrLogger.setFormatter(logging.Formatter(logging.BASIC_FORMAT))
logging.getLogger().addHandler(stderrLogger)

Since React 0.12 the API is slightly changed. The valid code to initialize myChild would be the following:

var Child = React.createClass({…});
var myChild = React.render(React.createElement(Child, {}), mountNode);
myChild.someMethod();

This is not as easy as it seems, some core library functions don't work when only str is overwritten (checked with Python 2.7), see this thread for examples How to make a class JSON serializable Also, try this

import json

class A(unicode):
    def __str__(self):
        return 'a'
    def __unicode__(self):
        return u'a'
    def __repr__(self):
        return 'a'

a = A()
json.dumps(a)

produces

'""'

and not

'"a"'

as would be expected.

EDIT: answering mchicago's comment:

unicode does not have any attributes -- it is an immutable string, the value of which is hidden and not available from high-level Python code. The json module uses re for generating the string representation which seems to have access to this internal attribute. Here's a simple example to justify this:

b = A('b') print b

produces

'a'

while

json.dumps({'b': b})

produces

{"b": "b"}

so you see that the internal representation is used by some native libraries, probably for performance reasons.

In a node.js server console.log outputs to the terminal window, not to the browser's console window.

How are you running your server? You should see the output directly after you start it.

sql = "insert into Main (Firt Name, Last Name) values(textbox2.Text,textbox3.Text)";

(Firt Name) is not a valid field. It should be FirstName or First_Name. It may be your problem.

This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n and the output of np.add.reduce() are both scalars, this implies that the problem lies with xm and ym, the two of which are simply your x and y inputs minus their respective means.

Based on this, my guess is that your x and y inputs have different shapes from one another, making them incompatible for element-wise multiplication.

** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

Bash 4 has a coproc command which establishes a named pipe to a command and allows you to communicate through it.

If it's a CLOB why can't we to_char the column and then search normally ?

Create a table

CREATE TABLE MY_TABLE(Id integer PRIMARY KEY, Name varchar2(20), message clob);

Create few records in this table

INSERT INTO MY_TABLE VALUES(1,'Tom','Hi This is Row one');
INSERT INTO MY_TABLE VALUES(2,'Lucy', 'Hi This is Row two');
INSERT INTO MY_TABLE VALUES(3,'Frank', 'Hi This is Row three');
INSERT INTO MY_TABLE VALUES(4,'Jane', 'Hi This is Row four');
INSERT INTO MY_TABLE VALUES(5,'Robert', 'Hi This is Row five');
COMMIT;

Search in the clob column

SELECT * FROM MY_TABLE where to_char(message) like '%e%';

Results

ID   NAME    MESSAGE   
===============================

Underscore Mixins

Extending on @emil_lundberg's answer, you can also write a "mixin" if you're using Underscore to make a custom function for sorting if it's a kind of sorting you might repeat in an application somewhere.

For example, maybe you have a controller or view sorting results with sort order of "ASC" or "DESC", and you want to toggle between that sort, you could do something like this:

Mixin.js

_.mixin({
    sortByOrder: function(stooges, prop, order) {
      if (String(order) === "desc") {
          return _.sortBy(stooges, prop).reverse();
      } else if (String(order) === "asc") {
          return _.sortBy(stooges, prop);
      } else {
          return stooges;
      }
    }
})

Usage Example

var sort_order = "asc";
var stooges = [
  {name: 'moe', age: 40}, 
  {name: 'larry', age: 50}, 
  {name: 'curly', age: 60},
  {name: 'July', age: 35},
  {name: 'mel', age: 38}
 ];

_.mixin({
    sortByOrder: function(stooges, prop, order) {
    if (String(order) === "desc") {
        return _.sortBy(stooges, prop).reverse();
    } else if (String(order) === "asc") {
        return _.sortBy(stooges, prop);
    } else {
        return stooges;
    }
  }
})


// find elements
var banner = $("#banner-message");
var sort_name_btn = $("button.sort-name");
var sort_age_btn = $("button.sort-age");

function showSortedResults(results, sort_order, prop) {
    banner.empty();
    banner.append("<p>Sorting: " + prop + ', ' + sort_order + "</p><hr>")
  _.each(results, function(r) {
    banner.append('<li>' + r.name + ' is '+ r.age + ' years old.</li>');
  }) 
}

// handle click and add class
sort_name_btn.on("click", function() {
  sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'name', sort_order);
  showSortedResults(sortedResults, sort_order, 'name');
})

sort_age_btn.on('click', function() {
    sort_order = (sort_order === "asc") ? "desc" : "asc"; 
    var sortedResults = _.sortByOrder(stooges, 'age', sort_order);
  showSortedResults(sortedResults, sort_order, 'age');
})

Here's a JSFiddle demonstrating this: JSFiddle for SortBy Mixin

While the other answer is correct, here's the fastest way to just go ahead and configure Meld as your visual diff tool. Just copy/paste this:

git config --global diff.tool meld
git config --global difftool.prompt false

Now run git difftool in a directory and Meld will be launched for each different file.

Side note: Meld is surprisingly slow at comparing CSV files, and no Linux diff tool I've found is faster than this Windows tool called Compare It! (last updated in 2010).

I actually have the same issue.

This link is probably my best guess:

nodejs vs node on ubuntu 12.04

I did that to resolve my problem:

sudo apt-get --purge remove node 
sudo apt-get --purge remove nodejs 
sudo apt-get install nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node

You might want to have a look at this specification for CSV. Bear in mind that there is no official recognized specification.

If you do not now the delimiter it will not be possible to do this so you have to find out somehow. If you can do a manual inspection of the file you should quickly be able to see what it is and hard code it in your program. If the delimiter can vary your only hope is to be able to deduce if from the formatting of the known data. When Excel imports CSV files it lets the user choose the delimiter and this is a solution you could use as well.

You can use java System.properties, for using them from eclipse you could:

1. Add -Dlabel="label_value" in the VM arguments of the test Run Configuration like this:

2. Then run the test:

   import org.junit.Test;
   import static org.junit.Assert.assertEquals;
   
   public class Main {
       @Test
       public void test(){
           System.out.println(System.getProperty("label"));
           assertEquals("label_value", System.getProperty("label"));
       }
   }
   

3. Finally it should pass the test and output this in the console:

   label_value
   

my_hash = {:a => 5}
my_hash[:key] = "value"

<v-btn color="info" @click="eliminarTarea(item.id)">Eliminar</v-btn>

And for your JS:

this.listaTareas = this.listaTareas.filter(i=>i.id != id)

Yeah, eclipse sees the top directory as the working/root directory, for the purposes of paths.

...just thought I'd add some extra info. I'm new here! I'd like to help.

You could round to n digits precision with:

double round( double x )
{
const double sd = 1000; //for accuracy to 3 decimal places
return int(x*sd + (x<0? -0.5 : 0.5))/sd;
}

My version is not using anything but the standard C++11 library. It copes well with Excel CSV quotation:

spam eggs,"foo,bar","""fizz buzz"""
1.23,4.567,-8.00E+09

The code is written as a finite-state machine and is consuming one character at a time. I think it's easier to reason about.

#include <istream>
#include <string>
#include <vector>

enum class CSVState {
    UnquotedField,
    QuotedField,
    QuotedQuote
};

std::vector<std::string> readCSVRow(const std::string &row) {
    CSVState state = CSVState::UnquotedField;
    std::vector<std::string> fields {""};
    size_t i = 0; // index of the current field
    for (char c : row) {
        switch (state) {
            case CSVState::UnquotedField:
                switch (c) {
                    case ',': // end of field
                              fields.push_back(""); i++;
                              break;
                    case '"': state = CSVState::QuotedField;
                              break;
                    default:  fields[i].push_back(c);
                              break; }
                break;
            case CSVState::QuotedField:
                switch (c) {
                    case '"': state = CSVState::QuotedQuote;
                              break;
                    default:  fields[i].push_back(c);
                              break; }
                break;
            case CSVState::QuotedQuote:
                switch (c) {
                    case ',': // , after closing quote
                              fields.push_back(""); i++;
                              state = CSVState::UnquotedField;
                              break;
                    case '"': // "" -> "
                              fields[i].push_back('"');
                              state = CSVState::QuotedField;
                              break;
                    default:  // end of quote
                              state = CSVState::UnquotedField;
                              break; }
                break;
        }
    }
    return fields;
}

/// Read CSV file, Excel dialect. Accept "quoted fields ""with quotes"""
std::vector<std::vector<std::string>> readCSV(std::istream &in) {
    std::vector<std::vector<std::string>> table;
    std::string row;
    while (!in.eof()) {
        std::getline(in, row);
        if (in.bad() || in.fail()) {
            break;
        }
        auto fields = readCSVRow(row);
        table.push_back(fields);
    }
    return table;
}

However, if you do end up using rm instead of git rm. You can skip the git add and directly commit the changes using:

git commit -a

What you are doing here is setting the default default profile (the profile that is used on any bean if you don't specify the @Profile annotation) to be production.

What you actually need to do is set the default active profile, which is done like this:

spring.profiles.active=production

I dont know why all these complicated answers are on here but this is what I would do

where pdate >= CURRENT_TIMESTAMP -30

OR WHERE CAST(PDATE AS DATE) >= GETDATE() -30

The trick to triggering an asynchronous stylesheet download is to use a <link> element and set an invalid value for the media attribute (I'm using media="none", but any value will do). When a media query evaluates to false, the browser will still download the stylesheet, but it won't wait for the content to be available before rendering the page.

<link rel="stylesheet" href="css.css" media="none">

Once the stylesheet has finished downloading the media attribute must be set to a valid value so the style rules will be applied to the document. The onload event is used to switch the media property to all:

<link rel="stylesheet" href="css.css" media="none" onload="if(media!='all')media='all'">

This method of loading CSS will deliver useable content to visitors much quicker than the standard approach. Critical CSS can still be served with the usual blocking approach (or you can inline it for ultimate performance) and non-critical styles can be progressively downloaded and applied later in the parsing / rendering process.

This technique uses JavaScript, but you can cater for non-JavaScript browsers by wrapping the equivalent blocking <link> elements in a <noscript> element:

<link rel="stylesheet" href="css.css" media="none" onload="if(media!='all')media='all'"><noscript><link rel="stylesheet" href="css.css"></noscript>

You can see the operation in www.itcha.edu.sv

Microsoft should advertise this functionality of SSMS 2008. The feature you are looking for is built into the Generate Script utility, but the functionality is turned off by default and must be enabled when scripting a table.

This is a quick run through to generate the INSERT statements for all of the data in your table, using no scripts or add-ins to SQL Management Studio 2008:

1. Right-click on the database and go to Tasks > Generate Scripts.
2. Select the tables (or objects) that you want to generate the script against.
3. Go to Set scripting options tab and click on the Advanced button.
4. In the General category, go to Type of data to script
5. There are 3 options: Schema Only, Data Only, and Schema and Data. Select the appropriate option and click on OK.

You will then get the CREATE TABLE statement and all of the INSERT statements for the data straight out of SSMS.

If you're on Windows, you may find the config file my.ini it in this directory

C:\ProgramData\MySQL\MySQL Server 5.7\

You open this file in a text editor and look for this section:

# The TCP/IP Port the MySQL Server will listen on
port=3306

Then you change the number of the port, save the file. Find the service MYSQL57 under Task Manager > Services and restart it.

For single color foreground color

label.setForeground(Color.RED)

For multiple foreground colors in the same label:

(I would probably put two labels next to each other using a GridLayout or something, but here goes...)

You could use html in your label text as follows:

frame.add(new JLabel("<html>Text color: <font color='red'>red</font></html>"));

which produces:

Similiary to accepted answer what you could do is use react and react-router itself to provide you history object which you can scope in a file and then export.

history.js

import React from 'react';
import { withRouter } from 'react-router';

// variable which will point to react-router history
let globalHistory = null;

// component which we will mount on top of the app
class Spy extends React.Component {
  constructor(props) {
    super(props)
    globalHistory = props.history; 
  }

  componentDidUpdate() {
    globalHistory = this.props.history;
  }

  render(){
    return null;
  }
}

export const GlobalHistory = withRouter(Spy);

// export react-router history
export default function getHistory() {    
  return globalHistory;
}

You later then import Component and mount to initialize history variable:

import { BrowserRouter } from 'react-router-dom';
import { GlobalHistory } from './history';

function render() {
  ReactDOM.render(
    <BrowserRouter>
        <div>
            <GlobalHistory />
            //.....
        </div>
    </BrowserRouter>
    document.getElementById('app'),
  );
}

And then you can just import in your app when it has been mounted:

import getHistory from './history'; 

export const goToPage = () => (dispatch) => {
  dispatch({ type: GO_TO_SUCCESS_PAGE });
  getHistory().push('/success'); // at this point component probably has been mounted and we can safely get `history`
};

I even made and npm package that does just that.

Steps using XAMPP GUI:

Step-1: Click on Config button

Step-2: Click on Service and Port Settings button

Final step: Change your port and Save

This is fixable in the application code by setting the button's TransformationMethod, e.g.

mButton.setTransformationMethod(null);

From man 7 gitrevisions:

HEAD names the commit on which you based the changes in the working tree. FETCH_HEAD records the branch which you fetched from a remote repository with your last git fetch invocation. ORIG_HEAD is created by commands that move your HEAD in a drastic way, to record the position of the HEAD before their operation, so that you can easily change the tip of the branch back to the state before you ran them. MERGE_HEAD records the commit(s) which you are merging into your branch when you run git merge. CHERRY_PICK_HEAD records the commit which you are cherry-picking when you run git cherry-pick.

When compiling with -std=c++11, one can simply

  const char *s  = u8"\u0444";
  cout << s << endl;

In Angular UI Bootstrap 0.13.X, tooltip-html-unsafe has been deprecated. You should now use tooltip-html and $sce.trustAsHtml() to accomplish a tooltip with html.

https://github.com/angular-ui/bootstrap/commit/e31fcf0fcb06580064d1e6375dbedb69f1c95f25

<a href="#" tooltip-html="htmlTooltip">Check me out!</a>

$scope.htmlTooltip = $sce.trustAsHtml('I\'ve been made <b>bold</b>!');

To create an empty data frame, pass in the number of rows and columns needed into the following function:

create_empty_table <- function(num_rows, num_cols) {
    frame <- data.frame(matrix(NA, nrow = num_rows, ncol = num_cols))
    return(frame)
}

To create an empty frame while specifying the class of each column, simply pass a vector of the desired data types into the following function:

create_empty_table <- function(num_rows, num_cols, type_vec) {
  frame <- data.frame(matrix(NA, nrow = num_rows, ncol = num_cols))
  for(i in 1:ncol(frame)) {
    print(type_vec[i])
    if(type_vec[i] == 'numeric') {frame[,i] <- as.numeric(frame[,i])}
    if(type_vec[i] == 'character') {frame[,i] <- as.character(frame[,i])}
    if(type_vec[i] == 'logical') {frame[,i] <- as.logical(frame[,i])}
    if(type_vec[i] == 'factor') {frame[,i] <- as.factor(frame[,i])}
  }
  return(frame)
}

Use as follows:

df <- create_empty_table(3, 3, c('character','logical','numeric'))

Which gives:

   X1  X2 X3
1 <NA> NA NA
2 <NA> NA NA
3 <NA> NA NA

To confirm your choices, run the following:

lapply(df, class)

#output
$X1
[1] "character"

$X2
[1] "logical"

$X3
[1] "numeric"

MySQL function example:

Open the mysql terminal:

el@apollo:~$ mysql -u root -pthepassword yourdb
mysql>

Drop the function if it already exists

mysql> drop function if exists myfunc;
Query OK, 0 rows affected, 1 warning (0.00 sec)

Create the function

mysql> create function hello(id INT)
    -> returns CHAR(50)
    -> return 'foobar';
Query OK, 0 rows affected (0.01 sec)

Create a simple table to test it out with

mysql> create table yar (id INT);
Query OK, 0 rows affected (0.07 sec)

Insert three values into the table yar

mysql> insert into yar values(5), (7), (9);
Query OK, 3 rows affected (0.04 sec)
Records: 3  Duplicates: 0  Warnings: 0

Select all the values from yar, run our function hello each time:

mysql> select id, hello(5) from yar;
+------+----------+
| id   | hello(5) |
+------+----------+
|    5 | foobar   |
|    7 | foobar   |
|    9 | foobar   |
+------+----------+
3 rows in set (0.01 sec)

Verbalize and internalize what just happened:

You created a function called hello which takes one parameter. The parameter is ignored and returns a CHAR(50) containing the value 'foobar'. You created a table called yar and added three rows to it. The select statement runs the function hello(5) for each row returned by yar.

Simplest way I can think of:

a.append(a.pop(0))

netcat (nc.exe) is the right tool. I have a feeling that any tool that does what you want it to do will have exactly the same problem with your antivirus software. Just flag this program as "OK" in your antivirus software (how you do this will depend on what type of antivirus software you use).

Of course you will also need to configure your sysadmin to accept that you're not trying to do anything illegal...

$check_value = isset($_POST['my_checkbox_name']) ? 1 : 0;

Unfortunately, vars files do not have include statements.

You can either put all the vars into the definitions dictionary, or add the variables as another dictionary in the same file.

If you don't want to have them in the same file, you can include them at the playbook level by adding the vars file at the start of the play:

---
- hosts: myhosts

  vars_files:
    - default_step.yml

or in a task:

---
- hosts: myhosts

  tasks:
    - name: include default step variables
      include_vars: default_step.yml

The accepted answer:

function isNumberKey(evt){
    var charCode = (evt.which) ? evt.which : event.keyCode
    if (charCode > 31 && (charCode < 48 || charCode > 57))
        return false;
    return true;
}

It's good but not perfect. It works out for me, but i get a warning that the if-statement can be simplified.

Then it looks like this, which is way prettier:

function isNumberKey(evt){
    var charCode = (evt.which) ? evt.which : event.keyCode;
    return !(charCode > 31 && (charCode < 48 || charCode > 57));
}

Would comment the original post, but my reputation is too low to do so (just created this account).

Some how all the above solutions did not worked in hibernate 5.2.10.Final.

But setting the map to null as below worked for me:

playlist.setPlaylistadMaps(null);

This explains better: Postman docs

Request body

While constructing requests, you would be dealing with the request body editor a lot. Postman lets you send almost any kind of HTTP request (If you can't send something, let us know!). The body editor is divided into 4 areas and has different controls depending on the body type.

form-data

multipart/form-data is the default encoding a web form uses to transfer data. This simulates filling a form on a website, and submitting it. The form-data editor lets you set key/value pairs (using the key-value editor) for your data. You can attach files to a key as well. Do note that due to restrictions of the HTML5 spec, files are not stored in history or collections. You would have to select the file again at the time of sending a request.

urlencoded

This encoding is the same as the one used in URL parameters. You just need to enter key/value pairs and Postman will encode the keys and values properly. Note that you can not upload files through this encoding mode. There might be some confusion between form-data and urlencoded so make sure to check with your API first.

raw

A raw request can contain anything. Postman doesn't touch the string entered in the raw editor except replacing environment variables. Whatever you put in the text area gets sent with the request. The raw editor lets you set the formatting type along with the correct header that you should send with the raw body. You can set the Content-Type header manually as well. Normally, you would be sending XML or JSON data here.

binary

binary data allows you to send things which you can not enter in Postman. For example, image, audio or video files. You can send text files as well. As mentioned earlier in the form-data section, you would have to reattach a file if you are loading a request through the history or the collection.

UPDATE

As pointed out by VKK, the WHATWG spec say urlencoded is the default encoding type for forms.

The invalid value default for these attributes is the application/x-www-form-urlencoded state. The missing value default for the enctype attribute is also the application/x-www-form-urlencoded state.

In a very rare case, with custom segue, the top most view controller is not in a navigation stack or tab bar controller or presented, but its view is inserted to the top of key windown's subviews.

In such situation, it's necessary to check if UIApplication.shared.keyWindow.subviews.last == self.view to determine if the current view controller is the top most.

make sure that your path is pointing to .exe file in C:\Program Files\7-Zip (may in bin directory)

I have another solution that works fine if you have a local copy of the repository on the machine where you would like to create the export. In this case move to this repository directory, and enter this command:

GIT_WORK_TREE=outputdirectory git checkout -f

This is particularly useful if you manage a website with a git repository and would like to checkout a clean version in /var/www/. In this case, add thiscommand in a .git/hooks/post-receive script (hooks/post-receive on a bare repository, which is more suitable in this situation)

You can't do this in any cross-browser way. IE does have methods to enable "trusted" applications to use ActiveX objects to read/write files, but that is it unfortunately.

If you are looking to save user information, you will most likely need to use cookies.

For Linux:

git add * 
git commit -a --message "Initial Push All"
git push -u origin --all

enum Constants
{
    Abc = 1,
    Def = 2,
    Ghi = 3
}

...

int i = (int)Enum.Parse(typeof(Constants), "Def");

It seems that you catch not the exception you wanna catch out there :)

if the s is a socket.socket() object, then the right way to call .connect would be:

import socket
s = socket.socket()
address = '127.0.0.1'
port = 80  # port number is a number, not string
try:
    s.connect((address, port)) 
    # originally, it was 
    # except Exception, e: 
    # but this syntax is not supported anymore. 
except Exception as e: 
    print("something's wrong with %s:%d. Exception is %s" % (address, port, e))
finally:
    s.close()

Always try to see what kind of exception is what you're catching in a try-except loop.

You can check what types of exceptions in a socket module represent what kind of errors (timeout, unable to resolve address, etc) and make separate except statement for each one of them - this way you'll be able to react differently for different kind of problems.

Programmatically, you could use:

textView.setTextAppearance(android.R.style.TextAppearance_Large);

Here is the good function for pre PHP 5: I added GMT difference at the end, it's not hardcoded.

function iso8601($time=false) {
    if ($time === false) $time = time();
    $date = date('Y-m-d\TH:i:sO', $time);
    return (substr($date, 0, strlen($date)-2).':'.substr($date, -2));
}

git fsck --unreachable | grep commit should show the sha1, although the list it returns might be quite large. git show <sha1> will show if it is the commit you want.

git cherry-pick -m 1 <sha1> will merge the commit onto the current branch.

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

I'm lacking context, but this is working just fine:

List<BigInteger> nums = new ArrayList<BigInteger>();
Long max = Collections.max(nums).longValue(); // from BigInteger to Long...

As noted by others, $('ul').empty() works fine, as does:

$('ul li').remove();

         {
             cbsb.Items.Add(reader["BatchID"].ToString()); //cbsb is the combobox name
         }
  }

if (!secondaryPassword.equals(initialPassword)) 

You have to use the JSON.stringify() function included with the V8 engine that node uses.

var objToJson = { ... };
response.write(JSON.stringify(objToJson));

Edit: As far as I know, IANA has officially registered a MIME type for JSON as application/json in RFC4627. It is also is listed in the Internet Media Type list here.

Short form:

[s.pop(k) for k in list(s.keys()) if k not in keep]

As most of the answers suggest in order to maintain the conciseness we have to create a duplicate object be it a list or dict. This one creates a throw-away list but deletes the keys in original dict.

I also raced through the first install on ubuntu and selected the default 30 day trial version instead of the non-commercial version.

There is a blog on the syntevo site that addresses this issue.

After unpacking the tar file I had a dir called smartgithg-4_0_3. I moved this folder to my home directory and renamed it smartgit. After running ./bin/smartgithg.sh, another folder was created called .smartgit (note the . prefix).

I simply deleted the .smartgit folder (the dir tree with all the .xml files) and ran the ,/bin/smarthg.sh script again. The whole install process is repeated. Select the non commercial option when it appears.

$(document.body).on('hidden.bs.modal', function () {
    $('#myModal').removeData('bs.modal')
});

'&' --> '&'

'<' --> '&lt;'

'>' --> '&gt;'

I am proposing my idea about it against any disadvantages array_values( ) function, because I think that is not a direct get function. In this way it have to create a copy of the values numerically indexed array and then access. If PHP does not hide a method that automatically translates an integer in the position of the desired element, maybe a slightly better solution might consist of a function that runs the array with a counter until it leads to the desired position, then return the element reached.

So the work would be optimized for very large array of sizes, since the algorithm would be best performing indices for small, stopping immediately. In the solution highlighted of array_values( ), however, it has to do with a cycle flowing through the whole array, even if, for e.g., I have to access $ array [1].

function array_get_by_index($index, $array) {

    $i=0;
    foreach ($array as $value) {
        if($i==$index) {
            return $value;
        }
        $i++;
    }
    // may be $index exceedes size of $array. In this case NULL is returned.
    return NULL;
}

String s = "xyz";
for(int i = 0; i < s.length(); i++)
{
   char c = s.charAt(i);
}

Android SDK Build Tools are exactly what the name says they are; tools for building Android Applications.It is very important to use the latest build tools version (selected automatically by your IDE via the Android SDK) but the reason the old versions are left there is to support backward compatibility, that is If your projects depend on older versions of the Build Tools.

So, this is an old post, however I think I can contribute something to it.

You can always do something like this:

package com.dyna.test;  

import java.io.File;  
import java.lang.reflect.Constructor;  

public class DynamicClass{  

  @SuppressWarnings("unchecked")  
  public Object castDynamicClass(String className, String value){  
    Class<?> dynamicClass;  

    try  
    {  
      //We get the actual .class object associated with the specified name  
      dynamicClass = Class.forName(className);  



    /* We get the constructor that received only 
     a String as a parameter, since the value to be used is a String, but we could
easily change this to be "dynamic" as well, getting the Constructor signature from
the same datasource we get the values from */ 


      Constructor<?> cons =  
        (Constructor<?>) dynamicClass.getConstructor(new Class<?>[]{String.class});  

      /*We generate our object, without knowing until runtime 
 what type it will be, and we place it in an Object as 
 any Java object extends the Object class) */  
      Object object = (Object) cons.newInstance(new Object[]{value});  

      return object;  
    }  
    catch (Exception e)  
    {  
      e.printStackTrace();  
    }  
    return null;  
  }  

  public static void main(String[] args)  
  {   
    DynamicClass dynaClass = new DynamicClass();  

    /* 
 We specify the type of class that should be used to represent 
 the value "3.0", in this case a Double. Both these parameters 
 you can get from a file, or a network stream for example. */  
    System.out.println(dynaClass.castDynamicClass("java.lang.Double", "3.0"));  

    /* 
We specify a different value and type, and it will work as 
 expected, printing 3.0 in the above case and the test path in the one below, as the Double.toString() and 
 File.toString() would do. */  
    System.out.println(dynaClass.castDynamicClass("java.io.File", "C:\\testpath"));  
  }  

Of course, this is not really dynamic casting, as in other languages (Python for example), because java is a statically typed lang. However, this can solve some fringe cases where you actually need to load some data in different ways, depending on some identifier. Also, the part where you get a constructor with a String parameter could be probably made more flexible, by having that parameter passed from the same data source. I.e. from a file, you get the constructor signature you want to use, and the list of values to be used, that way you pair up, say, the first parameter is a String, with the first object, casting it as a String, next object is an Integer, etc, but somehwere along the execution of your program, you get now a File object first, then a Double, etc.

In this way, you can account for those cases, and make a somewhat "dynamic" casting on-the-fly.

Hope this helps anyone as this keeps turning up in Google searches.

A TextinputLayout is not a view, but a Layout, as very nicely described by Dimitrios Tsigouris in his blog post here. Therefore, you don't need a Style, which is for Views only, but use a Theme. Following the blog post, I ended up with the following solution:

Start in your styles.xml with

<style name="TextInputLayoutAppearance" parent="Widget.Design.TextInputLayout">
        <!-- reference our hint & error styles -->
        <item name="android:textColor">@color/your_colour_here</item>
        <item name="android:textColorHint">@color/your_colour_here</item>
        <item name="colorControlNormal">@color/your_colour_here</item>
        <item name="colorControlActivated">@color/your_colour_here</item>
        <item name="colorControlHighlight">@color/your_colour_here</item>
</style>

And in your layout add

<com.google.android.material.textfield.TextInputLayout
                android:theme="@style/TextInputLayoutAppearance"
...

Upgrade from Angular v6 to Angular v7

Version 7 of Angular has been released Official Angular blog link. Visit official angular update guide https://update.angular.io for detailed information. These steps will work for basic angular 6 apps using Angular Material.

ng update @angular/cli 
ng update @angular/core
ng update @angular/material

Upgrade from Angular v5 to Angular v6

Version 6 of Angular has been released Official Angular blog link. I have mentioned general upgrade steps below, but before and after the update you need to make changes in your code to make it workable in v6, for that detailed information visit official website https://update.angular.io .

Upgrade Steps (largely taken from the official Angular Update Guide for a basic Angular app using Angular Material):

1. Make sure NodeJS version is 8.9+ if not update it.

2. Update Angular cli globally and locally, and migrate the old configuration .angular-cli.json to the new angular.json format by running the following:

   npm install -g @angular/cli  
   npm install @angular/cli  
   ng update @angular/cli
   

3. Update all of your Angular framework packages to v6,and the correct version of RxJS and TypeScript by running the following:

   ng update @angular/core
   

4. Update Angular Material to the latest version by running the following:

   ng update @angular/material
   

5. RxJS v6 has major changes from v5, v6 brings backwards compatibility package rxjs-compat that will keep your applications working, but you should refactor TypeScript code so that it doesn't depend on rxjs-compat. To refactor TypeScript code run following:

   npm install -g rxjs-tslint   
   rxjs-5-to-6-migrate -p src/tsconfig.app.json
   

   Note: Once all of your dependencies have updated to RxJS 6, remove rxjs- compat as it increases bundle size. please see this RxJS Upgrade Guide for more info.

   npm uninstall rxjs-compat
   

6. Done run ng serve to check it.
   If you get errors in build refer https://update.angular.io for detailed info.

Upgrade from Angular v5 to Angular 6.0.0-rc.5

1. Upgrade rxjs to 6.0.0-beta.0, please see this RxJS Upgrade Guide for more info. RxJS v6 has breaking change hence first make your code compatible to latest RxJS version.

2. Update NodeJS version to 8.9+ (this is required by angular cli 6 version)

3. Update Angular cli global package to next version.

   npm uninstall -g @angular/cli
   npm cache verify
   

   if npm version is < 5 then use npm cache clean

   npm install -g @angular/cli@next
   

4. Change angular packages versions in package.json file to ^6.0.0-rc.5

   "dependencies": {
     "@angular/animations": "^6.0.0-rc.5",
     "@angular/cdk": "^6.0.0-rc.12",
     "@angular/common": "^6.0.0-rc.5",
     "@angular/compiler": "^6.0.0-rc.5",
     "@angular/core": "^6.0.0-rc.5",
     "@angular/forms": "^6.0.0-rc.5",
     "@angular/http": "^6.0.0-rc.5",
     "@angular/material": "^6.0.0-rc.12",
     "@angular/platform-browser": "^6.0.0-rc.5",
     "@angular/platform-browser-dynamic": "^6.0.0-rc.5",
     "@angular/router": "^6.0.0-rc.5",
     "core-js": "^2.5.5",
     "karma-jasmine": "^1.1.1",
     "rxjs": "^6.0.0-uncanny-rc.7",
     "rxjs-compat": "^6.0.0-uncanny-rc.7",
     "zone.js": "^0.8.26"
   },
   "devDependencies": {
     "@angular-devkit/build-angular": "~0.5.0",
     "@angular/cli": "^6.0.0-rc.5",
     "@angular/compiler-cli": "^6.0.0-rc.5",
     "@types/jasmine": "2.5.38",
     "@types/node": "~8.9.4",
     "codelyzer": "~4.1.0",
     "jasmine-core": "~2.5.2",
     "jasmine-spec-reporter": "~3.2.0",
     "karma": "~1.4.1",
     "karma-chrome-launcher": "~2.0.0",
     "karma-cli": "~1.0.1",
     "karma-coverage-istanbul-reporter": "^0.2.0",
     "karma-jasmine": "~1.1.0",
     "karma-jasmine-html-reporter": "^0.2.2",
     "postcss-loader": "^2.1.4",
     "protractor": "~5.1.0",
     "ts-node": "~5.0.0",
     "tslint": "~5.9.1",
     "typescript": "^2.7.2"
   }
   

5. Next update Angular cli local package to next version and install above mentioned packages.

   rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows 
   Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
   npm install --save-dev @angular/cli@next
   npm install 
   

6. The Angular CLI configuration format has been changed from angular cli 6.0.0-rc.2 version, and your existing configuration can be updated automatically by running the following command. It will remove old config file .angular-cli.json and will write new angular.json file.

   ng update @angular/cli --migrate-only --from=1.7.4

Note :- If you get following error "The Angular Compiler requires TypeScript >=2.7.2 and <2.8.0 but 2.8.3 was found instead". run following command :

npm install [email protected]

According to OpenCV cheat-sheet this can be done as follows:

IplImage* oldC0 = cvCreateImage(cvSize(320,240),16,1);
Mat newC = cvarrToMat(oldC0);

The cv::cvarrToMat function takes care of the conversion issues.

Once you're logged into phpmyadmin look on the top navigation for "Settings" and click that then:

"Features" >

Unfortunately changing it through the UI means that the changes don't persist between logins.

You can use the random functionality included within the additions to the standard library (TR1). Or you can use the same old technique that works in plain C:

25 + ( std::rand() % ( 63 - 25 + 1 ) )

First check for an error (N/A value) and then try the comparisation against cvErr(). You are comparing two different things, a value and an error. This may work, but not always. Simply casting the expression to an error may result in similar problems because it is not a real error only the value of an error which depends on the expression.

If IsError(ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value) Then
  If (ActiveWorkbook.Sheets("Publish").Range("G4").offset(offsetCount, 0).Value <> CVErr(xlErrNA)) Then
    'do something
  End If
End If

Tried other variants, this can be proper

    Logger logger = Logger.getLogger(MyClass.class.getName());        
    Level level = Level.ALL;
    for(Handler h : java.util.logging.Logger.getLogger("").getHandlers())    
        h.setLevel(level);
    logger.setLevel(level);
// this must be shown
    logger.fine("fine");
    logger.info("info");

Decompress the JAR file and look for the manifest file (META-INF\MANIFEST.MF). The manifest file of JAR file might contain a version number (but not always a version is specified).

It's valid to omit them in HTML4:

7.3 The HTML element
start tag: optional, End tag: optional

7.4.1 The HEAD element
start tag: optional, End tag: optional

http://www.w3.org/TR/html401/struct/global.html

In HTML5, there are no "required" or "optional" elements exactly, as HTML5 syntax is more loosely defined. For example, title:

The title element is a required child in most situations, but when a higher-level protocol provides title information, e.g. in the Subject line of an e-mail when HTML is used as an e-mail authoring format, the title element can be omitted.

http://www.w3.org/TR/html5/semantics.html#the-title-element-0

It's not valid to omit them in true XHTML5, though that is almost never used (versus XHTML-acting-like-HTML5).

However, from a practical standpoint you often want browsers to run in "standards mode," for predictability in rendering HTML and CSS. Providing a DOCTYPE and a more structured HTML tree will guarantee more predictable cross-browser results.

your syntax is completely wrong....you need to give findelement to the driver

i.e your code will be :

WebDriver driver = new FirefoxDriver();
WebeElement element ;

element = driver.findElement(By.xpath("//[@test-id='test-username']"); 

// your xpath is: "//[@test-id='test-username']"

i suggest try this :"//*[@test-id='test-username']"

you can add this property globally in javascript:

if( navigator.userAgent.match(/iPhone|iPad|iPod/i) ) {
    var styleEl = document.createElement('style'), styleSheet;
    document.head.appendChild(styleEl);
    styleSheet = styleEl.sheet;
    styleSheet.insertRule(".modal { position:absolute; bottom:auto; }", 0);
 }

here is my custom function

function reverse_substring(str,from,to){
  var temp="";
  var i=0;
  var pos = 0;
  var append;      
  for(i=str.length-1;i>=0;i--){
    //alert("inside loop " + str[i]);
    if(pos == from){
         append=true;
    }

    if(pos == to){
         append=false;
         break;
    }
    if(append){
         temp = str[i] + temp;
    }
    pos++;
  }
  alert("bottom loop " + temp);
}

var str = "bala_123";
reverse_substring(str,0,3);

This function works for reverse index.

Try this

SELECT * FROM
    (
        SELECT T.*, ROW_NUMBER() OVER() R FROM TABLE T
    )
    WHERE R BETWEEN 10000 AND 20000

I consider Ashwin's answer to be the most correct, my old answer is below.

docker run -dti foo bash

You can then enter the container and run bash with

docker exec -ti ID_of_foo bash

No need to install sshd :)

I would like to compliment Ram Narasimhans answer with some tips I found on an Excel blog

Non-uniformly distributed data can be plotted in excel in

• X Y (Scatter Plots)
• Linear plots with Date axis
  • These don't take time into account, only days.
  • This method is quite cumbersome as it requires translating your time units to days, months, or years.. then change the axis labels... Not Recommended

Just like Ram Narasimhan suggested, to have the points centered you will want the mid point but you don't need to move to a numeric format, you can stay in the time format.

1- Add the center point to your data series

+---------------+-------+------+
|    Time       | Time  | Freq |
+---------------+-------+------+
| 08:00 - 09:00 | 08:30 |  12  |
| 09:00 - 10:00 | 09:30 |  13  |
| 10:00 - 11:00 | 10:30 |  10  |
| 13:00 - 14:00 | 13:30 |   5  |
| 14:00 - 15:00 | 14:30 |  14  |
+---------------+-------+------+

2- Create a Scatter Plot

3- Excel allows you to specify time values for the axis options. Time values are a parts per 1 of a 24-hour day. Therefore if we want to 08:00 to 15:00, then we Set the Axis options to:

• Minimum : Fix : 0.33333
• Maximum : Fix : 0.625
• Major unit : Fix : 0.041667

Alternative Display:

Make the points turn into columns:

To be able to represent these points as bars instead of just point we need to draw disjoint lines. Here is a way to go about getting this type of chart.

1- You're going to need to add several rows where we draw the line and disjoint the data

+-------+------+
| Time  | Freq |
+-------+------+
| 08:30 |   0  |
| 08:30 |  12  |
|       |      |
| 09:30 |   0  |
| 09:30 |  13  |
|       |      |
| 10:30 |   0  |
| 10:30 |  10  |
|       |      |
| 13:30 |   0  |
| 13:30 |   5  |
|       |      |
| 14:30 |   0  |
| 14:30 |  14  |
+-------+------+

2- Plot an X Y (Scatter) Chart with Lines.

3- Now you can tweak the data series to have a fatter line, no markers, etc.. to get a bar/column type chart with non-uniformly distributed data.

The mPDF docs state that the first argument of Output() is the file path, second is the saving mode - you need to set it to 'F'.

$mpdf->Output('filename.pdf','F');

You may have different sets of checkboxes on the same form. Here is a solution that selects/unselects checkboxes by class name, using vanilla javascript function document.getElementsByClassName

The Select All button

<input type='checkbox' id='select_all_invoices' onclick="selectAll()"> Select All

Some of the checkboxes to select

<input type='checkbox' class='check_invoice' id='check_123' name='check_123' value='321' />
<input type='checkbox' class='check_invoice' id='check_456' name='check_456' value='852' />

The javascript

    function selectAll() {
        var blnChecked = document.getElementById("select_all_invoices").checked;
        var check_invoices = document.getElementsByClassName("check_invoice");
        var intLength = check_invoices.length;
        for(var i = 0; i < intLength; i++) {
            var check_invoice = check_invoices[i];
            check_invoice.checked = blnChecked;
        }
    }

To kill all detached screen sessions, include this function in your .bash_profile:

killd () {
for session in $(screen -ls | grep -o '[0-9]\{5\}')
do
screen -S "${session}" -X quit;
done
}

to run it, call killd

Standard input - this is the file handle that your process reads to get information from you.

Standard output - your process writes conventional output to this file handle.

Standard error - your process writes diagnostic output to this file handle.

That's about as dumbed-down as I can make it :-)

Of course, that's mostly by convention. There's nothing stopping you from writing your diagnostic information to standard output if you wish. You can even close the three file handles totally and open your own files for I/O.

When your process starts, it should already have these handles open and it can just read from and/or write to them.

By default, they're probably connected to your terminal device (e.g., /dev/tty) but shells will allow you to set up connections between these handles and specific files and/or devices (or even pipelines to other processes) before your process starts (some of the manipulations possible are rather clever).

An example being:

my_prog <inputfile 2>errorfile | grep XYZ

which will:

• create a process for my_prog.
• open inputfile as your standard input (file handle 0).
• open errorfile as your standard error (file handle 2).
• create another process for grep.
• attach the standard output of my_prog to the standard input of grep.

Re your comment:

When I open these files in /dev folder, how come I never get to see the output of a process running?

It's because they're not normal files. While UNIX presents everything as a file in a file system somewhere, that doesn't make it so at the lowest levels. Most files in the /dev hierarchy are either character or block devices, effectively a device driver. They don't have a size but they do have a major and minor device number.

When you open them, you're connected to the device driver rather than a physical file, and the device driver is smart enough to know that separate processes should be handled separately.

The same is true for the Linux /proc filesystem. Those aren't real files, just tightly controlled gateways to kernel information.

Adding to @David Roussel answer, classes may be loaded by multiple class loaders.

Lets understand how class loader works.

From javin paul blog in javarevisited :

ClassLoader follows three principles.

Delegation principle

A class is loaded in Java, when its needed. Suppose you have an application specific class called Abc.class, first request of loading this class will come to Application ClassLoader which will delegate to its parent Extension ClassLoader which further delegates to Primordial or Bootstrap class loader

• Bootstrap ClassLoader is responsible for loading standard JDK class files from rt.jar and it is parent of all class loaders in Java. Bootstrap class loader don't have any parents.

• Extension ClassLoader delegates class loading request to its parent, Bootstrap and if unsuccessful, loads class form jre/lib/ext directory or any other directory pointed by java.ext.dirs system property

• System or Application class loader and it is responsible for loading application specific classes from CLASSPATH environment variable, -classpath or -cp command line option, Class-Path attribute of Manifest file inside JAR.

• Application class loader is a child of Extension ClassLoader and its implemented by sun.misc.Launcher$AppClassLoader class.

NOTE: Except Bootstrap class loader, which is implemented in native language mostly in C, all Java class loaders are implemented using java.lang.ClassLoader.

Visibility Principle

According to visibility principle, Child ClassLoader can see class loaded by Parent ClassLoader but vice-versa is not true.

Uniqueness Principle

According to this principle a class loaded by Parent should not be loaded by Child ClassLoader again

I was trying to reinstall mysql, and I actually forgot to stop the server from my old install. To solve that, ps -ax | grep mysql, then kill [whatever PIDs]. But, then again, it's different for everybody. Like the other answers said, go to /usr/local/var/mysql/ and check your .err log file.

If you want a (almost) one-liner:

from collections import deque

d = {}
deque((d.setdefault(year, []).append(value) for year, value in source_of_data), maxlen=0)

Using dict.setdefault, you can encapsulate the idea of "check if the key already exists and make a new list if not" into a single call. This allows you to write a generator expression which is consumed by deque as efficiently as possible since the queue length is set to zero. The deque will be discarded immediately and the result will be in d.

This is something I just did for fun. I don't recommend using it. There is a time and a place to consume arbitrary iterables through a deque, and this is definitely not it.

1. index.html file should come under below location - src/resources/public/index.html OR src/resources/static/index.html if both location defined then which first occur index.html will call from that directory.

2. The source code looks like -

   package com.bluestone.pms.app.boot; 
   import org.springframework.boot.Banner;
   import org.springframework.boot.Banner;
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.springframework.boot.builder.SpringApplicationBuilder;
   import org.springframework.boot.web.support.SpringBootServletInitializer;
   import org.springframework.context.annotation.ComponentScan;
   
   
   
   @SpringBootApplication 
   @EnableAutoConfiguration
   @ComponentScan(basePackages = {"com.your.pkg"}) 
   public class BootApplication extends SpringBootServletInitializer {
   
   
   
   /**
    * @param args Arguments
   */
   public static void main(String[] args) {
   SpringApplication application = new SpringApplication(BootApplication.class);
   /* Setting Boot banner off default value is true */
   application.setBannerMode(Banner.Mode.OFF);
   application.run(args);
   }
   
   /**
     * @param builder a builder for the application context
     * @return the application builder
     * @see SpringApplicationBuilder
    */
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder 
     builder) {
       return super.configure(builder);
      }
   }
   

My case is a little different, I'm trying to create a mask from a power, but I thought I'd share the solution I found anyway.

Obviously, it only works for powers of 2.

Mask1 = 1 << (Exponent - 1);
Mask2 = Mask1 - 1;
return Mask1 + Mask2;

You can use the Like operator with a wildcard to determine whether a given substring exists in a string, for example:

If cell.Value Like "*Word1*" Then
'...
ElseIf cell.Value Like "*Word2*" Then
'...
End If

In this example the * character in "*Word1*" is a wildcard character which matches zero or more characters.

NOTE: The Like operator is case-sensitive, so "Word1" Like "word1" is false, more information can be found on this MSDN page.

ADB Build-Tools Will Not be downloaded automatically, by command android update sdk --no-ui

So for installing Buil-Tool type (in console):

android list sdk --all

Remember the number that is listed before the item and execute the following:

android update sdk -u --all --filter <number>

commands should be typed in /YourFolder/android-sdk-linux/tools

Also for remote folder (server opened by ssh for example) type:

**./android** list sdk --all
**./android** update sdk -u --all --filter <number>

For simple list of ADB packages type in terminal:

android list sdk

for install all packages:

android update sdk --no-ui

Or with filters (comma is separator):

android update sdk --no-ui --filter 3,5,8,14

You can parameterize each value, so something like:

string[] tags = new string[] { "ruby", "rails", "scruffy", "rubyonrails" };
string cmdText = "SELECT * FROM Tags WHERE Name IN ({0})";

string[] paramNames = tags.Select(
    (s, i) => "@tag" + i.ToString()
).ToArray();

string inClause = string.Join(", ", paramNames);
using (SqlCommand cmd = new SqlCommand(string.Format(cmdText, inClause))) {
    for(int i = 0; i < paramNames.Length; i++) {
       cmd.Parameters.AddWithValue(paramNames[i], tags[i]);
    }
}

Which will give you:

cmd.CommandText = "SELECT * FROM Tags WHERE Name IN (@tag0, @tag1, @tag2, @tag3)"
cmd.Parameters["@tag0"] = "ruby"
cmd.Parameters["@tag1"] = "rails"
cmd.Parameters["@tag2"] = "scruffy"
cmd.Parameters["@tag3"] = "rubyonrails"

No, this is not open to SQL injection. The only injected text into CommandText is not based on user input. It's solely based on the hardcoded "@tag" prefix, and the index of an array. The index will always be an integer, is not user generated, and is safe.

The user inputted values are still stuffed into parameters, so there is no vulnerability there.

Edit:

Injection concerns aside, take care to note that constructing the command text to accomodate a variable number of parameters (as above) impede's SQL server's ability to take advantage of cached queries. The net result is that you almost certainly lose the value of using parameters in the first place (as opposed to merely inserting the predicate strings into the SQL itself).

Not that cached query plans aren't valuable, but IMO this query isn't nearly complicated enough to see much benefit from it. While the compilation costs may approach (or even exceed) the execution costs, you're still talking milliseconds.

If you have enough RAM, I'd expect SQL Server would probably cache a plan for the common counts of parameters as well. I suppose you could always add five parameters, and let the unspecified tags be NULL - the query plan should be the same, but it seems pretty ugly to me and I'm not sure that it'd worth the micro-optimization (although, on Stack Overflow - it may very well be worth it).

Also, SQL Server 7 and later will auto-parameterize queries, so using parameters isn't really necessary from a performance standpoint - it is, however, critical from a security standpoint - especially with user inputted data like this.

If your iframe is from another domain, (cross domain), the other answers are not going to help you... you will simply need to use this:

var currentUrl = document.referrer;

and - here you've got the main url!

And why not to keep looping if two conditions are true? I think this is a more pythonic way:

dejaVu = True

while dejaVu:
    while True:
        ok = raw_input("Is this ok? (y/n)")
        if ok == "y" or ok == "Y" or ok == "n" or ok == "N":
            dejaVu = False
            break

Isn't it?

All the best.

There is BashSupport plugin for IntelliJ IDEA which checks the syntax.

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} />

I'm using Rails + Cucumber + Selenium Webdriver + PhantomJS, and I've been using a monkey-patched version of Selenium Webdriver, which keeps PhantomJS browser open between test runs.

If You're under AngularJS 1.5.3 or newer, You should consider to move to components instead of directives. Those works very similar to directives but with some very useful additional feautures, such as $onChanges(changesObj), one of the lifecycle hook, that will be called whenever one-way bindings are updated.

app.component('conversation ', {
    bindings: {
    type: '@',
    typeId: '='
    },
    controller: function() {
        this.$onChanges = function(changes) {
            // check if your specific property has changed
            // that because $onChanges is fired whenever each property is changed from you parent ctrl
            if(!!changes.typeId){
                refreshYourComponent();
            }
        };
    },
    templateUrl: 'conversation .html'
});

Here's the docs for deepen into components.

You have included a dependency on the SLF4J API, which is what you use in your application for logging, but you must also include an implementation that does the real logging work.

For example to log through Log4J you would add this dependency:

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>1.5.2</version>
    </dependency>

The recommended implementation would be logback-classic, which is the successor of Log4j, made by the same guys that made SLF4J and Log4J:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>0.9.24</version>
</dependency>

Note: The versions may be incorrect.

short answer, specific to OAuth2,

• HS256 user client secret to generate the token signature and same secret is required to validate the token in back-end. So you should have a copy of that secret in your back-end server to verify the signature.
• RS256 use public key encryption to sign the token.Signature(hash) will create using private key and it can verify using public key. So, no need of private key or client secret to store in back-end server, but back-end server will fetch the public key from openid configuration url in your tenant (https://[tenant]/.well-known/openid-configuration) to verify the token. KID parameter inside the access_toekn will use to detect the correct key(public) from openid-configuration.

Very late, but might be useful for others.

There are only two cases when the circle intersects with the rectangle:

• Either the circle's centre lies inside the rectangle, or
• One of the edges of the rectangle has a point in the circle.

Note that this does not require the rectangle to be axis-parallel.

(One way to see this: if none of the edges has a point in the circle (if all the edges are completely "outside" the circle), then the only way the circle can still intersect the polygon is if it lies completely inside the polygon.)

With that insight, something like the following will work, where the circle has centre P and radius R, and the rectangle has vertices A, B, C, D in that order (not complete code):

def intersect(Circle(P, R), Rectangle(A, B, C, D)):
    S = Circle(P, R)
    return (pointInRectangle(P, Rectangle(A, B, C, D)) or
            intersectCircle(S, (A, B)) or
            intersectCircle(S, (B, C)) or
            intersectCircle(S, (C, D)) or
            intersectCircle(S, (D, A)))

If you're writing any geometry you probably have the above functions in your library already. Otherwise, pointInRectangle() can be implemented in several ways; any of the general point in polygon methods will work, but for a rectangle you can just check whether this works:

0 = AP·AB = AB·AB and 0 = AP·AD = AD·AD

And intersectCircle() is easy to implement too: one way would be to check if the foot of the perpendicular from P to the line is close enough and between the endpoints, and check the endpoints otherwise.

The cool thing is that the same idea works not just for rectangles but for the intersection of a circle with any simple polygon — doesn't even have to be convex!

They take up different amounts of space and they have different ranges of acceptable values.

Here are the sizes and ranges of values for SQL Server, other RDBMSes have similar documentation:

• MySQL
• Postgres
• Oracle (they just have a NUMBER datatype really)
• DB2

Turns out they all use the same specification (with a few minor exceptions noted below) but support various combinations of those types (Oracle not included because it has just a NUMBER datatype, see the above link):

             | SQL Server    MySQL   Postgres    DB2
---------------------------------------------------
tinyint      |     X           X                
smallint     |     X           X         X        X
mediumint    |                 X
int/integer  |     X           X         X        X 
bigint       |     X           X         X        X

And they support the same value ranges (with one exception below) and all have the same storage requirements:

            | Bytes    Range (signed)                               Range (unsigned)
--------------------------------------------------------------------------------------------
tinyint     | 1 byte   -128 to 127                                  0 to 255
smallint    | 2 bytes  -32768 to 32767                              0 to 65535
mediumint   | 3 bytes  -8388608 to 8388607                          0 to 16777215
int/integer | 4 bytes  -2147483648 to 2147483647                    0 to 4294967295
bigint      | 8 bytes  -9223372036854775808 to 9223372036854775807  0 to 18446744073709551615 

The "unsigned" types are only available in MySQL, and the rest just use the signed ranges, with one notable exception: tinyint in SQL Server is unsigned and has a value range of 0 to 255

Here my static version:

public static void playAssetSound(Context context, String soundFileName) {
    try {
        MediaPlayer mediaPlayer = new MediaPlayer();

        AssetFileDescriptor descriptor = context.getAssets().openFd(soundFileName);
        mediaPlayer.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
        descriptor.close();

        mediaPlayer.prepare();
        mediaPlayer.setVolume(1f, 1f);
        mediaPlayer.setLooping(false);
        mediaPlayer.start();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

POSIX defines set of standards for an operating system or a program. The goal is to write new software that is compatible with UNIX-like systems.

For example a program runs on Linux is also can be compile and run on other UNIX-like systems like Solaris, HP-UX, and AIX etc..

The most popular examples are GNU Bash which is 100% POSIX compliance and gawk utility.

The short answer is: No. The only way to post images is through the mobile app.

From the Instagram API documentation: http://instagram.com/developer/endpoints/media/

At this time, uploading via the API is not possible. We made a conscious choice not to add this for the following reasons:

• Instagram is about your life on the go – we hope to encourage photos from within the app. However, in the future we may give whitelist access to individual apps on a case by case basis.
• We want to fight spam & low quality photos. Once we allow uploading from other sources, it's harder to control what comes into the Instagram ecosystem.

All this being said, we're working on ways to ensure users have a consistent and high-quality experience on our platform.

Try to use this variant:

<?php echo Yii::app()->createAbsoluteUrl('your_yii_application/?lg=pl', array('id'=>$model->id));?>

It is the easiest way, I guess.

The more easy way its by executing the next command:

ls -ls /usr/bin/python*

Output look like this:

/usr/bin/python           /usr/bin/python2.7        /usr/bin/pythonw
/usr/bin/python-config    /usr/bin/python2.7-config /usr/bin/pythonw2.7

Not tested but you can try something like this :

Declare @count as int
Set @count=1
Declare @inputFile varchar(max)
Declare @Sample Table
(id int,filepath varchar(max) ,Isexists char(3))

while @count<(select max(id) from yourTable)
BEGIN
Set @inputFile =(Select filepath from yourTable where id=@count)
DECLARE @isExists INT
exec master.dbo.xp_fileexist @inputFile , 
@isExists OUTPUT
insert into @Sample
Select @count,@inputFile ,case @isExists 
when 1 then 'Yes' 
else 'No' 
end as isExists
set @count=@count+1
END

Something like:

var divided = str.split("/~/");
var name=divided[0];
var street = divided[1];

Is probably going to be easiest

Create a file ~/.curlrc with the following content

cacert=/etc/ssl/certs/ca-certificates.crt

as follows

echo "cacert=/etc/ssl/certs/ca-certificates.crt" >> ~/.curlrc

Using equals() LocalDate does override equals:

int compareTo0(LocalDate otherDate) {
    int cmp = (year - otherDate.year);
    if (cmp == 0) {
        cmp = (month - otherDate.month);
        if (cmp == 0) {
            cmp = (day - otherDate.day);
        }
    }
    return cmp;
}

If you are not happy with the result of equals(), you are good using the predefined methods of LocalDate.

• isAfter()
• isBefore()
• isEqual()

Notice that all of those method are using the compareTo0() method and just check the cmp value. if you are still getting weird result (which you shouldn't), please attach an example of input and output

It's method syntax (which I find easier to read) but this might do it

Updated post comment

Use .FirstOrDefault() instead of .First()

With regard to the dates average, you may have to drop that ordering for the moment as I am unable to get to an IDE at the moment

var groupByReference = context.Measurements
                              .GroupBy(m => m.Reference)
                              .Select(g => new {Creation = g.FirstOrDefault().CreationTime, 
//                                              Avg = g.Average(m => m.CreationTime.Ticks),
                                                Items = g })
                              .OrderBy(x => x.Creation)
//                            .ThenBy(x => x.Avg)
                              .Take(numOfEntries)
                              .ToList();

Note:

• the following condenses and organizes other answers in this thread, esp the excellent work of Stefan Lasiewski and Serge Stroobandt
• Lasiewski and I recommend Ch 19 (Here Documents) in the Advanced Bash-Scripting Guide

The question (how to write a here document (aka heredoc) to a file in a bash script?) has (at least) 3 main independent dimensions or subquestions:

1. Do you want to overwrite an existing file, append to an existing file, or write to a new file?
2. Does your user or another user (e.g., root) own the file?
3. Do you want to write the contents of your heredoc literally, or to have bash interpret variable references inside your heredoc?

(There are other dimensions/subquestions which I don't consider important. Consider editing this answer to add them!) Here are some of the more important combinations of the dimensions of the question listed above, with various different delimiting identifiers--there's nothing sacred about EOF, just make sure that the string you use as your delimiting identifier does not occur inside your heredoc:

1. To overwrite an existing file (or write to a new file) that you own, substituting variable references inside the heredoc:

   cat << EOF > /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, with the variable contents substituted.
   EOF
   

2. To append an existing file (or write to a new file) that you own, substituting variable references inside the heredoc:

   cat << FOE >> /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, with the variable contents substituted.
   FOE
   

3. To overwrite an existing file (or write to a new file) that you own, with the literal contents of the heredoc:

   cat << 'END_OF_FILE' > /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, without the variable contents substituted.
   END_OF_FILE
   

4. To append an existing file (or write to a new file) that you own, with the literal contents of the heredoc:

   cat << 'eof' >> /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, without the variable contents substituted.
   eof
   

5. To overwrite an existing file (or write to a new file) owned by root, substituting variable references inside the heredoc:

   cat << until_it_ends | sudo tee /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, with the variable contents substituted.
   until_it_ends
   

6. To append an existing file (or write to a new file) owned by user=foo, with the literal contents of the heredoc:

   cat << 'Screw_you_Foo' | sudo -u foo tee -a /path/to/your/file
   This line will write to the file.
   ${THIS} will also write to the file, without the variable contents substituted.
   Screw_you_Foo
   

You should put all your words into some kind of Collection or List and then call it like this:

var searchFor = new List<string>();
searchFor.Add("pineapple");
searchFor.Add("mango");

bool containsAnySearchString = searchFor.Any(word => compareString.Contains(word));

If you need to make a case or culture independent search you should call it like this:

bool containsAnySearchString = 
   searchFor.Any(word => compareString.IndexOf
     (word, StringComparison.InvariantCultureIgnoreCase >= 0);

I met a similar error after adding jQuery-ui-tooltip component using bower. It downloads js + css files only, so I had to manually add images.

A good source to find all the images (for all standard themes) is this CDN.

You can implement Finite State Machine in two different ways.

Option 1:

Finite State machine with a pre-defined workflow : Recommended if you know all states in advance and state machine is almost fixed without any changes in future

1. Identify all possible states in your application

2. Identify all the events in your application

3. Identify all the conditions in your application, which may lead state transition

4. Occurrence of an event may cause transitions of state

5. Build a finite state machine by deciding a workflow of states & transitions.

   e.g If an event 1 occurs at State 1, the state will be updated and machine state may still be in state 1.

   If an event 2 occurs at State 1, on some condition evaluation, the system will move from State 1 to State 2

This design is based on State and Context patterns.

Have a look at Finite State Machine prototype classes.

Option 2:

Behavioural trees: Recommended if there are frequent changes to state machine workflow. You can dynamically add new behaviour without breaking the tree.

The base Task class provides a interface for all these tasks, the leaf tasks are the ones just mentioned, and the parent tasks are the interior nodes that decide which task to execute next.

The Tasks have only the logic they need to actually do what is required of them, all the decision logic of whether a task has started or not, if it needs to update, if it has finished with success, etc. is grouped in the TaskController class, and added by composition.

The decorators are tasks that “decorate” another class by wrapping over it and giving it additional logic.

Finally, the Blackboard class is a class owned by the parent AI that every task has a reference to. It works as a knowledge database for all the leaf tasks

Have a look at this article by Jaime Barrachina Verdia for more details

I would recommend having a look at the plyr package. It might not be as fast as data.table or other packages, but it is quite instructive, especially when starting with R and having to do some data manipulation.

> DF <- data.frame(A = c("1", "1", "2", "3", "3"), B = c(2, 3, 3, 5, 6))
> library(plyr)
> DF.sum <- ddply(DF, c("A"), summarize, B = sum(B))
> DF.sum
  A  B
1 1  5
2 2  3
3 3 11

Another easy method to sort an array of strings consists by using the NSString description property this way:

NSSortDescriptor *valueDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"description" ascending:YES];
arrayOfSortedStrings = [arrayOfNotSortedStrings sortedArrayUsingDescriptors:@[valueDescriptor]];

ClickOnce applications are stored under the user's profile at %LocalAppData%\Apps\2.0\.

From there, use the search function to find your application.

If you want to emulate ___.new() syntax you can do something along the lines of:

type Thing struct {
    Name string
    Num int
}
type Constructor_Thing struct {}
func (c CThing) new(<<CONSTRUCTOR ARGS>>) Thing {
  var thing Thing
  //initiate thing from constructor args
  return thing
}
var cThing CThing

func main(){
  var myThing Thing
  myThing = cThing.new(<<CONSTRUCTOR ARGS>>)
  //...
}

Granted, it is a shame that Thing.new() cannot be implemented without CThing.new() also being implemented (iirc) which is a bit of a shame...

Symfony 3 and newer

I recently made a function which creates a tree of form errors. This will be helpful for returning list of errors back to front-end. This is based on form types having:

'error_bubbling' => false

Code:

public static function getFormErrorsTree(FormInterface $form): array
{
    $errors = [];

    if (count($form->getErrors()) > 0) {
        foreach ($form->getErrors() as $error) {
            $errors[] = $error->getMessage();
        }
    } else {
        foreach ($form->all() as $child) {
            $childTree = self::getFormErrorsTree($child);

            if (count($childTree) > 0) {
                $errors[$child->getName()] = $childTree;
            }
        }
    }

    return $errors;
}

Output:

Array
(
    [name] => Array
        (
            [0] => This value is not valid.
        )

    [emails] => Array
        (
            [0] => Array
                (
                    [0] => Given e-mail is not valid.
                    [1] => Given e-mail is not valid #2.
                )
            [1] => Array
                (
                    [0] => Given e-mail is not valid.
                    [1] => Given e-mail is not valid #2.
                )

        )

)

Notice: I know that errors from deeper level fields can be overwritten if higher level has errors, but this is on purpose for my usage.

Headings are normally bold-faced; that has been turned off for this demonstration of size correspondence. MSIE and Opera interpret these sizes the same, but note that Gecko browsers and Chrome interpret Heading 6 as 11 pixels instead of 10 pixels/font size 1, and Heading 3 as 19 pixels instead of 18 pixels/font size 4 (though it's difficult to tell the difference even in a direct comparison and impossible in use). It seems Gecko also limits text to no smaller than 10 pixels.

Demo

Not sure if it is what you want, but just simple example:

var input = document.getElementById('input');

input.addEventListener("change", function() {
    var file  = this.files[0];
    var img = new Image();

    img.onload = function() {
        var sizes = {
            width:this.width,
            height: this.height
        };
        URL.revokeObjectURL(this.src);

        console.log('onload: sizes', sizes);
        console.log('onload: this', this);
    }

    var objectURL = URL.createObjectURL(file);

    console.log('change: file', file);
    console.log('change: objectURL', objectURL);
    img.src = objectURL;
});

May be this will help:

wget --no-check-certificate https://blah-blah.tld/path/filename

Once you have obtained the context in your onTap() you can also do:

Intent myIntent = new Intent(mContext, theNewActivity.class);
mContext.startActivity(myIntent);

In javascript without using jquery:

document.body.innerText = document.body.innerText.replace('actualword', 'replacementword');

Using Eclipe Oxygen command + Shift + c on macOSx Sierra will add/remove comments out multiple lines of code

You can simply use theatol()function:

#include <stdio.h>
#include <stdlib.h>

int main() 
{
    const char *c = "5";
    int d = atol(c);
    printf("%d\n", d);

}

Even if you cancel the animation in the ways above animation didStopSelector still runs. So if you have logic states in your application driven by animations you will have problems. For this reason with the ways described above I use the context variable of UIView animations. If you pass the current state of your program by the context param to the animation, when the animation stops your didStopSelector function may decide if it should do something or just return based on the current state and the state value passed as context.

The following shell script gives a nice tabular result of interfaces and IP addresses (excluding the loopback interface) It has been tested on a Solaris box

psql's inline help:

\h ALTER TABLE

Also documented in the postgres docs (an excellent resource, plus easy to read, too).

ALTER TABLE tablename ADD CONSTRAINT constraintname UNIQUE (columns);

This will insert a new element after the input field with id "password".

$(document).ready(function(){
  var newInput = $("<input name='new_field' type='text'>");
  $('input#password').after(newInput);
});

Not sure if this answers your question.

Default text size vary from device to devices

Normally, I just want to know if the object is nil or not.

So i use this function that just returns true when the object entered is valid and false when its not.

func isNotNil(someObject: Any?) -> Bool {
        if someObject is String {
            if (someObject as? String) != nil {
                return true
            }else {
                return false
            }
        }else if someObject is Array<Any> {
            if (someObject as? Array<Any>) != nil {
                return true
            }else {
                return false
            }
        }else if someObject is Dictionary<AnyHashable, Any> {
            if (someObject as? Dictionary<String, Any>) != nil {
                return true
            }else {
                return false
            }
        }else if someObject is Data {
            if (someObject as? Data) != nil {
                return true
            }else {
                return false
            }
        }else if someObject is NSNumber {
            if (someObject as? NSNumber) != nil{
                return true
            }else {
                return false
            }
        }else if someObject is UIImage {
            if (someObject as? UIImage) != nil {
                return true
            }else {
                return false
            }
        }
        return false
 }

The three possible solutions suggested here have different use cases.

1. Use .equals when comparing ObjectID on two mongoDocuments like this

   results.userId.equals(AnotherMongoDocument._id)

2. Use .toString() when comparing a string representation of ObjectID to an ObjectID of a mongoDocument. like this

   results.userId === AnotherMongoDocument._id.toString()

You can use the .prop(propertyName) function to get a property from the first element in the jQuery object.

var savedIndex = $(selectElement).prop('selectedIndex');

This keeps your code within the jQuery realm and also avoids the other option of using a selector to find the selected option. You can then restore it using the overload:

$(selectElement).prop('selectedIndex', savedIndex);

To print the N first characters you can remove the N+1 characters up to the end of line:

$ sed 's/.//5g' <<< "defn-test"
defn

__VA_ARGS__ is the standard way to do it. Don't use compiler-specific hacks if you don't have to.

I'm really annoyed that I can't comment on the original post. In any case, C++ is not a superset of C. It is really silly to compile your C code with a C++ compiler. Don't do what Donny Don't does.

cellspacing (distance between cells) parameter of the TABLE tag is precisely what you want. The disadvantage is it's one value, used both for x and y, you can't choose different spacing or padding vertically/horizontally. There is a CSS property too, but it's not widely supported.

function closeWindow() {
    netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
    alert("This will close the window");
    window.open('','_self');
    window.close();
}

closeWindow();

In case of Request to a REST Service:

You need to allow the CORS (cross origin sharing of resources) on the endpoint of your REST Service with Spring annotation:

@CrossOrigin(origins = "http://localhost:8080")

Very good tutorial: https://spring.io/guides/gs/rest-service-cors/

my solution was:

.parent {
    display: flex;
    flex-wrap: wrap;
}

.product {
    width: 240px;
    margin-left: auto;
    height: 127px;
    margin-right: auto;
}

To be honest, the comments accompanying the prototypes seem clear enough. Something like this should do the trick:

void compute_md5(char *str, unsigned char digest[16]) {
    MD5Context ctx;
    MD5Init(&ctx);
    MD5Update(&ctx, str, strlen(str));
    MD5Final(digest, &ctx);
}

where str is a C string you want the hash of, and digest is the resulting MD5 digest.

Certainly not the only way - you could prototype a method (against Object here but I certainly wouldn't suggest using Object for live code) to replicate C#/Java style comparison methods.

Edit, since a general example seems to be expected:

Object.prototype.equals = function(x)
{
    for(p in this)
    {
        switch(typeof(this[p]))
        {
            case 'object':
                if (!this[p].equals(x[p])) { return false }; break;
            case 'function':
                if (typeof(x[p])=='undefined' || (p != 'equals' && this[p].toString() != x[p].toString())) { return false; }; break;
            default:
                if (this[p] != x[p]) { return false; }
        }
    }

    for(p in x)
    {
        if(typeof(this[p])=='undefined') {return false;}
    }

    return true;
}

Note that testing methods with toString() is absolutely not good enough but a method which would be acceptable is very hard because of the problem of whitespace having meaning or not, never mind synonym methods and methods producing the same result with different implementations. And the problems of prototyping against Object in general.

You need a table variable:

declare @values table
(
    Value varchar(1000)
)

insert into @values values ('A')
insert into @values values ('B')
insert into @values values ('C')

select blah
from foo
where myField in (select value from @values)

after all these good examples adam shankman still can't make sense of it. I think you should open up some code and try it. The second you try a myStack.Push(1) and myStack.Pop(1) you really should get the picture. But by the looks of it, even that will be a challenge for you!

Perhaps you don't have to include the single quotes:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/&fileName=1.doc"

Update: Reading curl's manual, you could actually separate both fields with two --data:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/" --data "fileName=1.doc"

You could also try --data-binary:

curl --request POST 'http://localhost/Service' --data-binary "path=/xyz/pqr/test/" --data-binary "fileName=1.doc"

And --data-urlencode:

curl --request POST 'http://localhost/Service' --data-urlencode "path=/xyz/pqr/test/" --data-urlencode "fileName=1.doc"

try to implement Application_AuthenticateRequest instead of Application_Start.

this method has an instance for HttpContext.Current, unlike Application_Start (which fires very soon in app lifecycle, soon enough to not hold a HttpContext.Current object yet).

hope that helps.

If you just need sampling without replacement:

>>> import random
>>> random.sample(range(1, 100), 3)
[77, 52, 45]

random.sample takes a population and a sample size k and returns k random members of the population.

If you have to control for the case where k is larger than len(population), you need to be prepared to catch a ValueError:

>>> try:
...   random.sample(range(1, 2), 3)
... except ValueError:
...   print('Sample size exceeded population size.')
... 
Sample size exceeded population size

The command to separate a running job from the shell ( = makes it nohup) is disown and a basic shell-command.

From bash-manpage (man bash):

disown [-ar] [-h] [jobspec ...]

Without options, each jobspec is removed from the table of active jobs. If the -h option is given, each jobspec is not removed from the table, but is marked so that SIGHUP is not sent to the job if the shell receives a SIGHUP. If no jobspec is present, and neither the -a nor the -r option is supplied, the current job is used. If no jobspec is supplied, the -a option means to remove or mark all jobs; the -r option without a jobspec argument restricts operation to running jobs. The return value is 0 unless a jobspec does not specify a valid job.

That means, that a simple

disown -a

will remove all jobs from the job-table and makes them nohup

Take a look at this tutorial for how to use SQL inside VBA:

http://www.ehow.com/how_7148832_access-vba-query-results.html

For a query that won't return results, use (reference here):

DoCmd.RunSQL

For one that will, use (reference here):

Dim dBase As Database
dBase.OpenRecordset

The documentation is quite sketchy as far as definitive resolutions go. After some research, here's the solution I came to: Android splash screen image sizes to fit all devices

It's basically guided towards splash screens, but it's perfectly applicable to images that should occupy full screen.

Public variable declarations in classes is the easiest way:

On target class:

public class MyFragment extends Fragment {
    public MyCallerFragment caller; // Declare the caller var
...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
           Bundle savedInstanceState) {
        // Do what you want with the vars
        caller.str = "I changed your value!";
        caller.i = 9999;
        ...
        return inflater.inflate(R.layout.my_fragment, container, false);
    }
...
}

On caller class:

public class MyCallerFragment extends Fragment {
    public Integer i; // Declared public var
    public String str; // Declared public var
        ...
            FragmentManager fragmentManager = getParentFragmentManager();
            FragmentTransaction transaction = fragmentManager.beginTransaction();

            myFragment = new MyFragment();
            myFragment.caller = this;
            transaction.replace(R.id.nav_host_fragment, myFragment)
                    .addToBackStack(null).commit();
        ...
}

If you want to use the main activity it is easy too:

On main activity class:

public class MainActivity extends AppCompatActivity {
    public String str; // Declare public var
    public EditText myEditText; // You can declare public elements too.
                                // Taking care that you have it assigned
                                // correctly.
...
}

On called class:

public class MyFragment extends Fragment {
    private MainActivity main; // Declare the activity var
...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
           Bundle savedInstanceState) {
        // Assign the main activity var
        main = (MainActivity) getActivity();

        // Do what you want with the vars
        main.str = "I changed your value!";
        main.myEditText.setText("Wow I can modify the EditText too!");
        ...
        return inflater.inflate(R.layout.my_fragment, container, false);
    }
...
}

Note: Take care when using events (onClick, onChanged, etc) because you can be on a "fighting" situation where more than one assign a variable. The result will be that the variable sometimes does not will change or will return to the last value magically.

For more combinations use your creativity. :)
